+# Doma
+
+Doma is a database access framework for Java that provides compile-time code generation, type-safe query building, and SQL template support. It offers a unique approach to database programming with annotation processing for compile-time validation and zero runtime dependencies.
+
+## Key Features
+
+- **Compile-time Code Generation**: Uses annotation processing to generate DAO implementations and validate SQL queries at compile time
+- **Type-safe Criteria API**: Build queries programmatically with full type safety and IDE support
+- **Two-way SQL**: Write SQL templates that work both as standalone SQL and within the framework
+- **Entity Associations**: Support for one-to-one, one-to-many, and many-to-one relationships
+- **Zero Dependencies**: Runs independently without requiring additional libraries
+- **Multi-language Support**: First-class support for Java and Kotlin
+- **Framework Integration**: Seamless integration with Spring Boot, Quarkus, and other frameworks
+
+## Architecture
+
+Doma follows a code-first approach where:
+1. You define entities using annotations
+2. Annotation processors generate DAO implementations at compile time
+3. SQL queries are validated against entity definitions
+4. Runtime execution uses generated, optimized code
+
+## Use Cases
+
+- Applications requiring complex SQL queries with type safety
+- Projects needing compile-time validation of database operations
+- Systems where performance and minimal dependencies are critical
+- Teams preferring SQL-centric development over ORM abstractions
